acterized particularly vby a plunger having a cupped valve which closesupon a raised valve seat', thevplungerA being guided by a` standard.. Arell tube is so located with respect to the valve that as the water isdischarged through the valve it will be carried upQ through the tube forthe purpose of refilling the bowl as the tank is lfilling. The inventionis illustrated in the accompanying drawings in .Which-f igure 1 is aside elevation of the valve.

2 is a sectional View thereon'. eferring specifically to the drawings,the tank bottom is indicated at 6. The inlet pipe 7 extends through thisbottom and is provided with a lock nut 8 and a coupling nut 9 under saidbottom. At the topthe pipe section 7 is provided or formed` with atapered or frusto conical valve seat 10 at the basejof which-a ange 11projects to rest on Athe tank bottom, against which it4 is tightlyclamped byfthe'lock nut 8. .At oneside 'the yflange forms a base for thelstandard 12, which is preferably formed integral withthe baseandwhichhas at the top the plunger or valvestem guide 13 which overhangsY thevalve seat and is in line therewith. The valve stem or plunger 14 worksat its upper it has a cupped head 15 containing 'packing 16, and theflanges or sides ofthe cup itl laround or inclose theupper end of thevalve seat, whereby the direction of discharge through the valve isdownward on the outer sides of the valve seat. The valve seat tf tingalso supports .the refill tub-e 17, the [lower end of v vlch Aopensthrough or beside `the 'base' of the standard 12 with its entranceopposite the tapered side of the valve seat residing 1 plunger.

, valve is operated bya iioat 18 at o'ne end ofa lever 19 the other endof which is pivoted to the valve stem at 20, the lever being fulcruinedto the standard at 21. The absence of numerous or complicated parts isobvious.

lith respect to operation, when the float. falls the valve is lifted andthe water flows outnoiselessly and down the outside of the valve. seatto the bottom of the tank. At t-he same time va certain amount of theAwater will enter the inlet to the refill tube andyr will be forced upthrough the same, from which it will flow into the liush pipe as usual,for the intended purpose. By placing the inlet and the -rell tube inline With the flow of Water this result is accomplished without furthermeans. The depending flanges or sides of the-cup, around the taperedvalve seat, in connection withv the guide 13, prevent thevalveffrom'getting `out of position. lVhe'n the float rises the f valveis closed, pressing the packing to -conftact with the top of the valveseat inv an obvious manner. I

Anfespecially advantageous feature of the valve is its simplicity andthe few parts required, there beingbut two main castings, that is, thevalve seat vcasting andv the I claim :l 1. The combination valveiseatand opening at the end thereof, a cupped valve surrounding said seat-andmovable toand from the salne, the sides of the valve causing reverseflow along the outside of the seat, and a refill tube having its inletopposite the lbase of the scat and in the line of said reverse vliow. i

2. The combination of-an inlet pipe, a tapered valve seat at the topthereof, a cupped valve surrounding the seat and movableand down to andfrom the same, the sides the valve causing flow downwardly be- .side thevalve seat, a refill tube havingits inlet op osite the base of the seatand in the line of ow beside the same,and a float of a pipe having a.
